Profiles, can these be measured without a model?

[MrComment]

How does PC-DMIS relate any random or ordered series of measured points, to the CAD model when dimensioning a profile? Is it simply just the measured points closest distance in any direction to the nearest surface of the CAD model?

In either case is there a way to measure a profile without using a CAD?

Thanks

You Have To Know The Nominals Of The Object You Are Measuring. You Can Manually Put Them In While Taking Your Points Or Offline ..

The only way you can measure a profile (to dimension) is if you have nominal XYZ data. You don't need a cad model, but if you don't have one, then YOU will have to type in the XYZ nominal (and IJK as well) for each and every point.

correct.........without cad the profile macro still needs to know where the points are supposed to be in order to do it's calculations....you will have to volunteer alittle nominal info....B

Profiles of flat surfaces is relatively easy. Contours are something else.
For flat surfaces, in the proper alignment, you can use autofeatures Vector Points and edit to proper nominal and vector and then just repeat changing side to side and front to back nominals to create pattern of hits you want to take. Then create a feature set and there you are.

Use COPY and PASTE w/ PATTERN for flat surfaces
